The documented behavior of csv.QUOTE_MINIMAL is that fields containing the quote character should be quoted.

However, running:

import csv

with open('trash.csv', 'w') as csvfile:
  writer = csv.writer(csvfile, quoting=csv.QUOTE_MINIMAL, doublequote=False, escapechar='\\')
  writer.writerow(['"'])

> cat trash.csv
\"

My expectation is that this field would have been quoted (e.g., "\""), as it contains the quote character (escaped). If this is intended behavior, then the documentation should be clarified, or if it's not, this is a bug.
